Здесь я использую один список флажков, в котором у нас есть следующий элемент
Apr-16,May-16,Jun-16,jul-16,Aug-16,Sep-16,Oct-16,Nov-16,Dec-16,Jan-16,Feb-16,Mar-16
Когда мы выбираем флажок за 16 апреля из списка cheboxlist, Gridview показывает ежемесячную плату за 16 апреля, а когда мы выбираем 16 апреля, 16 мая, тогда Gridview показывает подробную информацию о сборах за 16 апреля, 16 мая.
Когда мы выбираем 16 мая, 16 июня, 16 июля, тогда Gridview показывает 16 мая, 16 июня, 16 июля. Подробности о трех комиссиях.
Мне нужен результат:
Теперь я хочу посчитать сумму определенного столбца в моем представлении сетки
